Other mistake: In the first Alien movie, a few drops of spilled Alien blood eats through two floors of the space freighter. Yet at the end of this movie when the Alien violently explodes and its entire blood supply is vaporized, the surrounding steel wall and floor are not affected. They do not melt, and Ripley is not affected by the blood spray even though she is only a few feet away.
Continuity mistake: When Ripley is looking for the Alien in a room full of pipes and chains, she spots what looks like the head of the Alien and slowly walks towards it, talking to it as she goes. When she smashes it with a metal pipe, loads of bugs fall out and it's a completely different pipe we are looking at, it's not smooth and long but a corner piece.
Answer: According to the Alien 3 Movie Special magazine from 1992, yes, there was a scene where the Sulaco explodes as the EEV pod ejects, damaging the guidance systems. Apparently it was filmed but not included in the final cut.
